I PETER LA TOURRETTE, OF VESTAL, NEW YORK. i

Specification forming part of Letters Patent No. 16l,525, dated March 30, 1875; application tiled December 21, 1874.

i i i To all whom it may concern: Be it known that I, PETER LA TOUERETTE, I oi' Vestal, Broome county, New York, have invented a Ghurning-Machine, of which the foli lowing is a specification: This invention relates to that class of churns operated by a hand-crank or pulley. The nag ture of the invention consists in the application of cranks having adjustable throws, in combination with the frame and gear work of p the machine, which will hereafter be fully expi'ained, the object of the invention being to adjust the throw of the cranks, and thereby increase or diminish the stroke of the dash for `-churns partially lled, or for churns of l different sizes; also to facilitate the operation of churning.

Figure l in the accompanying drawings represents a machine embodying my invention. i Figs. 2 and 3 are the two parts of the cranks detached.

The crank A is made in two sections, one of which has a slot, a, made lengthwise of the i center connection, of sufficient length to allow of the required altera-tion of the throw. The f other has two projecting bolts, b b, set on a line in the outer connection. These bolts t the slot a, and guide the adjustment ot' the two cranks, which, when in position, form a double crank with opposite throws. They are r secured together by screw-nuts c con the ends of the bolts b b. The side pieces d d of the f cranks have a slot running parallel with the i slot a in the center, for the connection and adjustment of the sectional crank-shaft e, which is secured in position by a bolt and nut. The F shaft e has its bearing on the top of the frame B, and has a pulley, C, on the end driven by a belt from the driving-pulley D, which is i i i r hung on the side of the machine. This pulley is actuated by a hand-crank, E. The connecting-rods ff have two prongs, and work astride projecting guides g g, attached to a cross-piece in the frame B. The ends of these guides are perforated for the dash-rods h h to work in. These dash-rods are connected with the connecting-rods f f by pins t' i, which pass through the dash-rods h la. F F are the churns of the ordinary construction.

lVhen the churning is light, and there is not cream enough to till the churns to their usual capacity, the throw of the crank A is shortened, so as to elevate the dash only to the surface of the cream. By loosening up the nuts c c and sliding up the slotted center connection c to the required point and securing it, the shaft e is then adjusted on a line and secured, when the machine is ready for operation.

By this invention the dash may be adjusted to a small quantity of cream, or any sized churn may be used.

I claim as my inventionl. The combination of the double adjustable crank-plate A and plates el d with the shafts e e, substantially as set forth.

2. The combination of the adjustable crank A, of the frame B, pulley C on the end of shaft e, driving pulley D, hung on the side of frame B, hand-crank E, projecting guides g g, ani connecting-rods f f, all constructed substantially as herein described, for the purpose set forth.

PETER LA TOURRETTE.
